Analogies are only worth so much, but please note that Apple stillsells optical drives. They didn't leave the optical market out in the cold. Another example: Apple stubbornly refused to accept right click as a mouse feature for many years, because a single click was more elegant, and their elegant design did not "need" right click. Totally their call as it's their product. But people just used other mice or means of right-click until they came around to what the market wanted.
